What is stereoisomers and chirality?
Answers
HEY MATE HERE IS YOUR ANSWER--
In a pair of enantiomers, all of the chiral centers are of the opposite configuration. ... The definition of diastereomers is simple: if two molecules are stereoisomers (same molecular formula, same connectivity, different arrangement of atoms in space) but are not enantiomers, then they are diastereomers by default.
Answer:
Explanation:
stereoisomer- Two molecules are described as stereoisomers if they are made of the same atoms connected in the same sequence, but the atoms are positioned differently in space.
The difference between stereoisomers can only be seen when the three-dimensional arrangement of the molecules is considered.Stereoisomers can be subdivided into optical isomers and geometric isomers.
Optical isomers
These are molecules which are mirror images of one another. Often these mirror image molecules are referred to as enantiomers.
Geometric isomers-
When people refer to geometric isomers they are usually referring to cis-trans isomers. Cis-trans isomers can be found when rotation around a chemical bond is impossible, as seen in molecules with double and triple bonds.
Chirality
An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superposed onto it. Conversely, a mirror image of an achiral object, such as a sphere, cannot be distinguished from the object. A chiral object and its mirror image are called enantiomorphs.
Human hands are perhaps the most universally recognized example of chirality. The left hand is a non-superimposable mirror image of the right hand; no matter how the two hands are oriented, it is impossible for all the major features of both hands to coincide across all axes.This difference in symmetry becomes obvious if someone attempts to shake the right hand of a person using their left hand, or if a left-handed glove is placed on a right hand. In mathematics, chirality is the property of a figure that is not identical to its mirror image.
